The current issue is iOS 26.1’s wallpaper renderer crashes in a tight loop if the default wallpaper isn’t installed. It isn’t under Xcode.

I have macos crash reporting turned off, but crashreport pins the CPU for a few minutes on each ios wallpaper renderer crash. I always have the iOS simulator open, so two hours battery, max.

I killed crashreport and it spun the cpu on some other thing.

In macos 25, there’s no throttle for mds (spotlight), and running builds at a normal developer pace produces about 10x more indexing churn than the Apple silicon can handle.
